When rendering/bouncing or freezing offline the sound of Kaivo Presets changes compared to what it sounded with realtime playback. This seems to be affected strongly by the Nonlinear Knobs of the physical models.
The Nonlinear Knobs usually bring a more "feedback"-prone behaviour with them, but with Ableton's render for example the Sound of Acoustic Bass 2 goes from sth that sounds like a plucked bass to something that sounds like a continously bowed bass (even when the notes are off). After rendering or freezing this constant sound will stay till the plugin is removed or reloaded.
I am not an expert when it comes to audio programming, but I am pretty sure this is not intended behaviour.
Thanks for the report. Of course Kaivo should sound the same when rendered. So I'll treat this as a bug and investigate.
The audio engine renders the same samples in either case, and I never have heard any difference in testing. My first guess is this is a problem with MIDI notes or controllers not being played back correctly.
You could try different buffer settings in Live to see if there is any difference.
